Resolved error on log fastcgi header

[Stephan Griesel]

Hi guys,

Hope someone can help. Noticed one of my sites go down and error message service unavailable message is displayed. I had a look at the logs for the specific site in Plesk and found the following error:

AH01067: Failed to read FastCGI header
Connection reset by peer: AH01075

I am convinced this is buggy plugin but can't pinpoint it. Where can I find the PHP logs so I can confirm this?

I am running 12.5.30 Update #52
